To answer this question, I would do the following

1. Find out the area of the small hexagon in terms of x. To do this, basically make triangles from the centre of the hexagon, to each vertex. Then, work out the area of one of the triangles using 1/2 x base x height and times it by how many triangles were in the hexagon. [Note: to work out the area of the small triangle, you're gonna need to do SOH CAH TOA].

2. Once you got the area of the small hexagon in terms of x, times it by p^2 to get the area of the large hexagon. (Remember, if the length scale factor is p, the area scale factor is p^2). Once you times it by p^2, take away your two areas and factorise - you'll end up with what they've given you.

My solution, look at it after trying it yourself
